RUBBER PUMP-BUCKET.

SPECIFICATION forming part of Letters Patent NO. 605,707, dated June 14,1898.

Application filed November ll, 1897. Serial No; 658,149. (No model.)

To ctZZ whom it may concern:

Be it known that I, HENRY C. FRESHOUR, a citizen of the UnitedStates,residing at Bridgeport, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements in RubberPump-Buckbe a full, clear, and exact description of the invention, suchas will enable others skilled in the art to which it appertains to makeand fact that there is no surplus stock, less expen-' sive to producethan any practical chain-, pump bucket now upon the market.

With these ends in view I have devised the novel pu mp-bucket which Iwill now describe, referring by number to the accompanying drawings,forming part of this specification, in which- Figure 1 is a plan View ofmy novel pumpbucket, the side in view being the side which I ordinarilymake the under side, although that is not a matter of importance; Fig.2, an edge view, the fiat side of the bucket being uppermost; and Fig. 3is a section on the line m to in Fig. 1.

1 denotes the table of my novel bucket, the fiat side of which isordinarilyplaced uppermost, as shown in Fig. 2.

2 denotes the hub, which is provided with a central opening 3 to receivethe shank of a chain-link, and at denotes brackets or supporting-ribsextending from the hub nearly to the edge of the table and serving assupports therefor, the brackets in connection with the hub being stiffenough to hold the table absolutely rigid under ordinary circumstances,but being sufficiently flexible to permit the table to yield slightly atthe edges should it be necessary in use. or supporting-ribs is not ofthe essence of my invention. In the present instance I have shown sixbrackets or supporting-ribs, which number 'I have found quite sufiicientin prac- .tice. ets; and I do hereby declare the following to Y Inpractice the hub, table, and brackets or supporting-ribs are molded in asingle piece. It will be seen that all surplus stock is dispensed with,thus making the number of my novel buckets run higher to the pound. I

have found in practice that they are sufficiently flexible at the edgesto cause them to fit a pump-stock closely. It will be observed that theradial ribs or brackets 4 are arranged edgewise vertically or at rightangles to the table 1 and that they are highest or deepest at theirinner ends and slope thence downward outwardly toward their outer ends,which terminate at or near the periphery of the said table. From thisedgewise arrangement of the said ribs or brackets relative to said tableit will be obvious that they afford a maximum amount of rigidity tosupport or strengthen said table with a minimum amount of stock requiredin their formation or construction, and they thus render the tablesufficiently rigid, so that the bucket may be-used either side up inlifting water; also, when thus constructed and arranged they are adaptedto serve as guards to protect the edges of the bucket-table fromabrasion in entering the penstock or pipe.

Having thus described my invention, I claim A chain-pump bucketcomprising a table, a hub, and a series of radial ribs or bracketsintegral with the said hub and table, said ribs or brackets beingdisposed edgewise vertically or at right angles to said table, and beinghighest or deepest at their inner ends and sloping thence outwardly.

In testimony whereof I affix my signature in presence of two witnesses.

HENRY C. FRESHOUR.
